The aim is to describe the external morphology of the opisthosoma in Oligobrachia mashikoi, a species from Tsukumo Bay.
Collected samples of Oligobrachia mashikoi from Tsukumo Bay, Japan.
Examined the external morphology of the opisthosoma in detail.
Documented segment number, arrangement of setae, and morphological differences between dorsal and ventral sides.
Identified over 50 segments in the opisthosoma.
Noted distinct morphological differences between dorsal and ventral sides.
Described the presence of 4 lines of longitudinally arranged setae and a sucker at the tip.
